U Be it kinownlthat I, Wrnnmivr J.-E WMAN, a citizen of the United 'fStates, residing :at

-Gliicago, iin the county of (look and State o-f lillinois, have inwented certain newaand useful Improvements in End Gates for Dump Elrucks, of which the following is a specification. v

This 'iiiwenrtion relates to an and gate or door, which is especially adapted to be used for the bodies' of automdbile trucks having means for tipping or tilting the body for dumpingthe same. These trucks are frequently used for hauling various kinds of material, including earth or excavated material, and are frequently filled by means of steam shovels' Whenthese trucksare dumped, it is sometimes desirable tohave the load discharged at some distance from the rear end of the truck body, while at other times it is desirable to have the load discharged close to the body.

The objects of the presentv invention are to provide a simple form of end gate or closure for truck 'bodieswhich may enable the load to be discharged close to the end,

or at some distance therefrom; to provide an end gate having combinedpivots and catches at the top and bottom thereof, whereby the" gate "may be swung upwardly or downwardly to discharge the load; to provide an arrangement whereby the gate may be swung up above the top of the body, to

insure a'full discharge space; to provide a combined catch and hinge member'for an end gate; and in general, to provide such an improvedconstruction as will 'be, described hereinafter.

In the accompanying drawings showing one form of my device:

F'gurev 1 is a side view of the rear end of a truck body shown in discharging position; 5

, Figure 2 is a detail plan view of the hinge arrangement. I 1

As shown in these drawings, 3 represents a truck body which may be of any ordinary or preferred form of construction, and which is provided with an end gate 4, Which is connected at its lower edge, to the body by combined hinge and catch devices, whereby the door may'qswing or be freed at its loweredge. In the present instance, these combined hinges and catches comprise U-shaped bearings 5, which are securedto the body 3, and are adapted to receive the pintles *6 which {project from the rlo werie esof-ithe door 4. The bearings 5 are provided with 'holes 7 for receiving locking {PIIIS 8,vrfor holding the pintles in position.

an; *upper edge or the door :is provided with hinge 'fu III'lS =9, which projject forwardly and have rpintles 10, which rest on the top Off the :box or body 3 which-is hiormed so that lit furnishes :a suitable ibearrng therefor.

As shown in the drawings such bearingi's provided by having plates or flanges arranged at the top of the sides of the body 3, this being a more or lesscommon form of construction in bodies for trucks in tended for heavy loads. Hooks 11 are hinged at 12 to the upper portions of the sides of the body, and engage with the pintles 10 to hold them in proper position.

These hooks preferably extend through holes 13 in the upper part of the sides, andare also preferably provided with handles 14 for swinging the same. It will be seen from the drawings that when these hooks are moved downwardly to engage with the pintles or hinge member 10, they draw in on these members to draw the end gate tight and then hold it in this position. These hooks with their hinge straps being positioned on the top of the box, also serve to protect the same, as they are preferably made quite strong and heavy.

When the door or gate .L is to be used as a chute for discharging material some distancefrom the end of the body, the hooks 11 areraised, and the gate swings outwardly from the top to the lowered position shown in dotted lines in Figure 1.

When the gate is to be swung upwardly, the pins 8 are removed and the gate may then swing on the upper hinges to the raised ing the gate without having any parts projecting for any considerable distance above the b ody. This is an important feature, as

any projectingparts are apt to interfere when the trucks are being loaded by steam shovels. 7

It Will be noted that changes maybe made in the details of construction to adapt this invention to different forms of bodies", and means (not'shown) may be provided for manipulating the catch members from the drivers seat, and therefore I do not wish to be limited to the exact arrangement herein shown and described, except as specified in the following claims:

l. The combination with a truck body having outwardly projecting flanges at the top thereof with holes therethrough, of hinge members secured to the flanges, hooks pivoted to said hinge members and adapted to project down through said holes in the flanges, said hooks having handles for swinging the same, an end gate pivoted at the bottom of the body and having pins adapted to rest on the flanges in advance of the hooks and to be engaged by the hooks for holding the door in closed position and also to provide a hinge whereby the bottom of the door may be swung outwardly, substantially as described.

2. The combination with a truck body having flanges at'the top thereof, of an end gate, combined hinge and catch fastenings at the bottom of the gate, pins at the top of the gate adapted to rest on the flange,-

hooks pivotally secured to the flange and projecting downwardly through holes behind the pins and adapted to engage with the pins for holding the gate in closed position and also for providing a hinge for the gate, said hooks being arranged so that they project a minimum distance above the top of the body, substantially as described.

'WILLiAM J NEWMAN.
